Description

Technical Field

[0001] This utility model relates to the field of display application technology, and in particular to an AR film. Background Technology

[0002] AR film, commonly known as anti-reflective coating, is applied to the display screen of electronic products to effectively reduce light reflection and achieve a higher transmittance effect. It is currently widely used in new high-end mobile phones, computers, car displays, rearview mirrors and other display fields.

[0003] Existing AR films on the market are generally applied to screens, and due to the uniformity of the AR coating thickness, they will show a rainbow effect. The overall visual appearance may be bluish, purple, or reddish, and the color stability is insufficient. The first impression is not ideal, which affects the user experience. Utility Model Content

[0012] As a preferred embodiment of this utility model, the pressure-sensitive adhesive layer is an organosilicon pressure-sensitive adhesive, acrylic adhesive, or OCA with a thickness of 10-50 micrometers.

[0013] The beneficial effects of this utility model are as follows: The structure of this utility model is ingeniously designed, with a reasonable combination of AR coating group and iridescent coating.
